CHICAGO (AP) — President Joe Biden has delivered his valedictory address to the Democratic National Convention, saying, “I gave my best to you.” He basked in a long ovation that reflected the energy released by his decision to cede the stage to Vice President Kamala Harris. Biden received a hero’s welcome weeks after many in his party were pressuring him to drop his bid for reelection. The opening night of the convention in Chicago was designed as a handoff from the incumbent to his hand-picked successor — albeit four years before he intended for her to follow him. A visibly emotional Biden was greeted by a more than four-minute-long ovation and chants of “Thank you Joe.”
